I'd appreciate your help with this Lachnum collection.
Host: indet. herbaceous stem.
Asci: without croziers.
Paraphyses: without strongly refractive VBs.
Hairs: without oxalate crystals, not inflated, at least up to 95 µm long. In one apothecium covered by an orange substance (probably an artifact).
Ascospores: ca. 6.5-8 x 1.2-1.8 µm.
It seems like L. reynoutriae would be close...
Best wishes,
Gernot

Re : Lachnum sp.
Hallo Gernot
at least the substrate is clearly Reynoutria. But I think the species fits also.

Re : Lachnum sp.
Super, danke, Zotto!
I wasn't sure about the substrate because I didn't see any Reynoutria at that location.
Best wishes,
Gernot

Re : Lachnum sp.
I actually see a bit difference to my Reynoutria-photos in cross section, but Rumex in comparison has a different appearance (rilled instead of smooth).

Re : Lachnum sp.
Would it help if I took more photos? If so, of which parts of the substrate?

Re : Lachnum sp.
Der Stängel ist nich hohl, sondern markgefüllt. Wäre Helianthus an dem Standort eine Option?:

Re : Lachnum sp.
Der Standort ist eine feuchte Straßenböschung, darüber stockt ein Fichtenwald, und auch in der weiteren Umgebung gibt es keine Sonnenblumenfelder – Helianthus würde ich daher ausschließen...
Schöne Grüße

Re : Lachnum sp.
Das Mark hat mich in der Tat auch irritiert!
